Abstract
The purpose of this study was to evaluate several aspects of the Aircraft Carrier-Tactical Support Center (CV-TSC) console design. These variables were tested individually in order to isolate their effect and make recommendations for the overall console design. Six trackball devices, three number entry methods (keyboard number row, keyboard number pad, and separate number pad), and three methods of gross navigation (trackball only, touch screen, and navigation buttons) were evaluated. All tests involved simple tasks with timing and accuracy measures collected, as well as subjective feedback.
The results of the study indicated that trackball 6 outperformed the others in most objective measures and was also the most preferred trackball. There were no conclusive performance results for the number entry test; however participants indicated a preference for a number pad, either separate or integrated with the keyboard. The touch screen method of gross navigation was the best performer, although participants preferred the trackball-only condition.
